What is Development Length of Bars?
What is Development Length of Bars? The development length of a bar can be defined as the minimum length of the bar which shall be projected or embedded into concrete beyond any section to develop its full strength. For a Beam column joint, the portion of the bar that is embedded in the column via beam main bar is termed as development length In the case of axial tension or axial compression, this bar is termed as anchorage length and for flexural tension or flexural compression, we call it development length. Why Development Length is provided? It develops a safe bond between surfaces of the bar and concrete to ensure that during ultimate loading conditions, any failure due to slippage of the reinforcement bar does not occur. Further, development length is provided for smooth transferring of the stresses developed in any section to the adjoining sections. At beam-column joint, development bars are used to transfer stresses of beams into the column. If you want to learn more about...
